nx{comp{,shad},proxy}: add configure flag --enable-cxx11 to enable and setup optional C++11 support.
Use AX_CXX_COMPILE_STDCXX(_11) from autotools archive.
Note: should only be used in tandem. Make sure that each component
either uses the C++11 ABI or none uses it. Mixing and matching libraries
and binaries with different C++ ABIs might lead to weird errors.
